CHARLES F. WRAY, OF ROCHESTER, NEW YORK, ASSIGNOR TO THE NATIONAL BRASSMANUFACTURING COMPANY, F ROCHESTER, NEW YORK, A CORPORATION OF NEW YORK.

LUBRICATOE CUP.

Application filed April 14, 1921.

To all lit/tcm 'it na/,zy conce/w1.'

Be it known that I, Crm-mina lf. "rv'nar, a citizen of the United Statesof jAmerica, residing at Rochester, in the county of Monroe and citateof New York, have invented certain new and useful lmproven'ients inLubricator Cups, oi' which the vfolioiving a specilicaton.

My invention relates to lubricator cup.; and has for its purpose toafford a simplified and economical cmis'truction, embodying anarrangement of such a nature that the parts can be readily manufacturedand assemlglled.

and also pern'iit-ting the tlovv of oil from the cup to be easilycontrolled.

The invention comlnehends various features of advantage, all of whichwill clearly appear from the following description, in conjunction withthel accompanying dran'- ings` the novel features being pointed out 1uthe claims at the end of the description.

In the drawings:

Figure 1 is a side elevation of a lubricator cup, showing theapplication of my invention in its preferred embodiment.

Figure 2 is an enlarged vertical sectional view taken centrally.

Figure 3 is a horizontal sectional view on the line 3-3 of Figure 1.

Figure 4 is a sectional view on line i-et of Figure 3, and

Figure 5 is a sectional view on line 5-5 of Figure 2, looking upwardly.

The invention is illustrated, as applied to a conventional forni oflubricator cup, including the bottom 1, oil outlet 2, and centraltubular support B having openings 1 through which oil passes from thecup to the outlet 2. Surrounding the central tubular support- 3 is theside wall 5, `which is usually made of glass, and rests upon thebottom 1. f

6 designates the cover which is seated on the upper end of the side Wall5, and is provided ivith a non-circular opening at its center, suchopening being preferably in the form of a double D. The cover 6 isadapted to receive in said opening a supporting collar 7` vwhich retainsthe cover and has noncircular and preferably double ifi-shaped exteriorcross section corresponding with the opening in the cover, andc(wperatingthere- With so to prevent relative 'turning of the collar andcover v/hen the part-.1 are assembled as shown in Figure 2.

Serial No. l161,5?i5.

The supporting collar 7 .is interiorly threaded, and at its lovver endengages an eX- teriorly threaded portion on the upper end of the tubularsupport il. The supporting collar 7 carries the valve mechanism, as willbc described presently, and in assembling these parts, the supportingcollar 7 is ii st inserted into the cover (i, and then by turning thecover, which can be easily engaged at its outer edge, the collar islikewise turned by reason of the non-rotative connection with the coveralready described, and the collar is thus brought into attachment withthe central tubular support and holds the cover in place. During suchassembling, it is desirable to prevent separation of the supportingcollar and cover and this is accomplished by movable or yieldableretaining means, as Willnow be described.

rthe collar f is provided with a shoulder or flanged portion 8 whichoverlies the outer face of the cover 6, and adjacent to the inner faceof said cover, the collar 7 is provided With annular recesses 9.'Mount-ed on the cover is a pivoted slide 10, Which normally closes thefilling opening 1l, and is retained in its normal position by a coilspring 12. One end of the spring 12 is iixedly connected to the post 13upon which the slide is mounted, While the free end of said spring 12engages one of said recesses 9 in the collar, as shovvn in Figures i and5. ln this manner, the spring 12 performs the double function of'actuating the pivoted slide 10, and of locking the collar 7 in itsnormal relationship to the cover 6, so as to prevent separation of saidparts.

The valve mechanism includes a valve rod 14, carried by a sleeve 15, thelatter be- .ing exteriorly threaded, and engaging the upper end of theinterior-ly threaded collar 7. The valve rod 14, and the valve at thelower end thereof, are moved to open or `closed position by the usualfinger lever 16,

and in order to adjust the degree of opening or closing of the valve, itis necessary to turn sleeve 15. To this end, the sleeve is provided withan operating device, preferably in the form of an integral lrnurled heador finger piece 17, and by turning the finger piece 17, the sleeve iselevated or lowered Within the collar 7 and with it the valve and itscontrolling lever 1G. It is essential that the sleeve 15 be retained inits adjusted position, and this is preferably accomplished llt).

by a coil spring 18, located between the collar 7 and the finger piece17, and exerting pressure in both directions. The finger piece 17 isprovided with a pocket 19, and vthe collar 7 is provided with a pocket20, to receive the corresponding ends of the spring 18, which bears withsuiiicient friction against the linger piece 1 7 to retain the sleeve l5against accidental displacement.

Although the invention has been disclosed with reference to a particularembodiment, it is not limited to the precise construction set forth, andthis application is intended. to cover any mo'dications or departuresthat may properly come Within the scope oi? the 'following claims.
